I thought that no one in Gensokyo other than us here knew Murasa's story, but... I'd suspect she's heard the legends as well.

About Murasa... As well as about her weakness.

If she's really from the same region as Murasa, I'd much rather build a better relationship with her...

But if she, for whatever unknown reason, wants to harm Murasa...

Umm... I heard the children talking about her. Apparently that ushi-oni looks like a woman who comes to sell fish in the Village.
